Abstract: Ensemble de portique (2) et de palette (90) utilisant des caméras (46) à scintillation afin d'acquérir des données émises par des agents radiopharmaceutiques préalablement administrés à un patient. Les agents radiopharmaceutiques s'accumulent dans une région étudiée prédéterminée à l'intérieur du patient. Le portique (2) peut effectuer des tomographies corps entier et des scanographies individuelles par émission photonique (SPECT). Le portique (2) comporte deux caméras (46) à scintillation montées de manière diamétralement opposée sur un anneau (24) de rotation et à proximité immédiate. Chaque caméra (46) peut être déplacée radialement par rapport à l'anneau (24) de rotation, simultanément avec la rotation de l'anneau (24). Le portique (2) peut être déplacé le long d'une paire de voies (12) de déplacement, de sorte qu'une palette (52, 54) sur laquelle un patient est allongé passe sur celle-ci. L'ensemble de palettes dispose d'un chariot de stockage, lequel supporte une palette (52) plate, sensiblement rectangulaire, sur un cadre (68) coulissant, et une palette (54) incurvée sur un ensemble (68) de prolongement. Le chariot (50) de stockage peut coulisser à l'opposé du portique (2) ou à proximité de ce dernier (2). Lorsque ledit chariot (50) de stockage est à proximité du portique (2), les deux palettes (52, 54) peuvent être facilement transférées jusqu'à un support (110, 112) de palettes réglable verticalement, utilisé pendant les examens.

Abstract: A modular multilayer interwiring substrate is disclosed wherein various parts of relatively small size are produced separately as 'sub-units' (1), which are finally combined to form the multilayer interwiring structure (22). Hereby each individual layer of the final structure is formed by joining a respective set of unit parts (1) in one plane. The whole multilayer substrate is then built by stacking these layers, preferably in such a manner, that a lateral displacement occurs from one layer to the other and vertical neighboured unit parts (1) will have their edges not in line. The unit parts (1) itself carry on their front and/or rear side at least one layer of conductive material (8, 9) which can be individually patterned into diverse interconnection lines (5). Throughconnections (6) from front to backside of the units (1) are performed by a desired set or a standardised array of via holes (6) or openings filled with conductive material thus revealing electric paths penetrating the units. By connecting desired throughputs (6) to the respective conduction lines (5) each unit (1) can form an individual part of a more complex multilayer interwiring structure (22).

Abstract: The invention proposes a thermostatic valve (10) for controlling the temperature of the cooling liquid of an internal combustion engine, in which an adjustable supporting part (26) is provided as an abutment for the working plunger (14) of a thermostat based on an expanding material which actuates the valve disc (17). The supporting part (26) is arranged coaxially to the working piston (14) and connected to the latter and is acted upon in the opposite direction to the valve closing direction by means of a spring (35) and pressed into its initial position. The supporting part (26) is adjustable counter to the action of the spring (35) by means of an actuating member (36), in particular a thermostatic working element (37), this working element (37) being electrically heatable. By this means, the working range of the thermostatic valve (10) can be adjusted, for example to a higher opening temperature (winter operation). If the heating fails, the thermostatic valve (10) is adjusted automatically to the other working position by the spring (35) acting on the supporting part (26), resulting, for example, in a lower opening temperature. <IMAGE>

Abstract: A power screed (2) for smoothing freshly poured concrete (36) and a method of operating the screed is described. The screed has adjustable vertical support means (28) to account for uneveness in the supporting surface (34). The support means are located near each side of the screed and are controlled by hydraulic motors (38). The screed can be adjusted manually and/or automatically through the use of an external laser source (44). When concrete is poured, it is roughly smoothed by rakes or similar tools. The screed is then advanced over the concrete with the lowest level of the screed determining the level of the surface of the concrete. Where the supporting surface upon which the concrete is poured is uneven, the screed can be raised or lowered to ensure that the upper surface of the concrete is level. The support means are each composed of two screw jacks (30) mounted on a ski (32). As the screed advances through the concrete, the support means leaves a track in the concrete which must be smoothed and filled manually. Presently, the level of a screed is controlled by bulkheads located at either side of the screed. The bulkheads must be installed in such a manner that an upper level of th bulkheads corresponds to an upper level of the finished concrete. With the present invention, the bulkheads can be eliminated.

Title: Method and apparatus for reducing emissions of n 2?o when burning nitrogen-containing fuels in fluidized bed reactors.
Inventor: HILTUNEN MATTI
IPC: F23J15/08
Filed: 1991-04-15
Abstract: The amount of N2O emission from a fluidized bed reactor is reduced by adding a hydrogen radical providing additive (e.g. a hydrogen containing fuel such as natural gas or alcohol) to the flue gases discharged from the fluidized bed. Sufficient oxygen is present in the flue gases-either by addition with the additive, or by addition of an excess to the combustion chamber-so that the additive reacts with the oxygen, typically raising the temperature of the flue gases (e.g. from about 700 DEG -900 DEG  C. to about 950 DEG -1100 DEG  C.) so that N2O production is reduced about 10-90%. The additive may be injected in or just prior to a cyclone for separating particles from the flue gases. In a gas discharge immediately after the cyclone, just prior to a superheater of a convection section, or in a combustion chamber just prior to a gas turbine.
